Critically Endangered
Sakhalin taimen
Parahucho perryi
The Sakhalin taimen (Sakhalin taimen, syn.
The salmonid
Fish over 30 cm (1 ft) long are almost exclusively piscivores, while the young feed mostly on aquatic insects. The average specimens caught have weighed around 5 kg (11 lb).
Range and habitat
Sakhalin taimen are found in the Northwest Pacific: Sakhalin Island (Russia), the Island of Hokkaidō (Japan), and parts of the far eastern Russian mainland. The earliest known fossils of the genus are from the mid-late Miocene-aged Agnevo Formation of Sakhalin Island.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Diet
Salmonids need cold, oxygenated water and a clean gravel or open-lake feeding ground. Endemic whitefishes collapse when the lake is eutrophied or fished out.
In crisis
The population has been in general decline for a century at least, with contributory factors among them degradation of the environment by logging, oil exploration and change of land use to agriculture. The fish is caught by commercial fishing as bycatch, by recreational anglers and illegally by poaching, and present populations are estimated to be less than 5% of their historic levels. The International Union for Conservation of Nature has rated the fish as being critically endangered.
The global population of the species has dwindled in recent years for a variety of reasons. Other considerable pressures include bycatch in the commercial salmon fisheries of Russia and Japan, as well as illegal fishing practices in Russia.
